Synopsis. Frons projecting above eye; 3d anten- 
nal segment frequently finely pointed (fig. 363); 
4 orbital bristles, upper ors reclinate, lower of

rior ones; wing length 2.5-3 mm, radial veins 
dark, normal, medial veins virtually colorless, 
costa ending just after end of vein R 4+5; squama 
and fringe silvery; male genitalia with aedeagus 
(figs. 364, 365) having d istinctive curvature of 
distiphallus complex, basal sclerites bending 
gradually (not at right angles, contrast A. am -

Synopsis. Closely resembling A. utahensis but 
without contrast between radial and medial veins, 
all veins pale, yellowish; wing length 2.5- 
3 mm; 3d antennal segment angular but bluntly so, 
not finely pointed (fig. 367); male genitalia with 
aedeagus having medial section bending at obtuse 
angle to paired tubules of distiphallus (fig. 
368), basal sclerites (fig. 369) bending at right 
angle at apical 3d; surstylus essentially as in A. 
utahensis (fig. 366). ~ 
Host/Early Stages. In America, reared from Agropy- 
ron repens , Hordeum jubatum , Secale cereale , and 
Triticum aestivum (Frick, 1959). In Europe, also 
from Avena sativa . Larva forming broad blotch 
mine; posterior spiracles widely separated, each 
with 3 bulbs (see A. nigrella , fig. 384); puparium 
reddish orange or paler* yellowish brown.
